Mitsubishi 00JCPU User Manual page 465

*1: Among the sequence-started modules on the base unit(s), the module closest to the High Performance model QCPU is assigned to the
1st module and the others are assigned in ascending order.
*2: The time-limit value of the internal timer is set by default.
In the PLC system tab of the PLC parameter dialog box, the value can be changed within the range of 0.5ms to 1000ms in increments of
0.5ms.
*3: This is applicable to the module whose serial number (first five digits) is "07032" or later.
*4: In the case of a multiple CPU system, this is applicable only to CPU No.1 when serial numbers (first five digits) of all CPU modules are
"07032" or later.
*5: After processing for "I32 (all of stop errors)" is completed, the High Performance model QCPU stops.
*6: Execution of I32 to I48 will be disabled (DI) if the system is powered on or when the High Performance model QCPU is reset.
To use any of I32 to I48, enable the interrupt with the IMASK instruction.
For the IMASK instruction, refer to the following.
MELSEC-Q/L Programming Manual (Common Instruction)
*7: Set an interval value of the internal timer in the High speed interrupt setting dialog box, which can be opened from the System interrupt
settings area in the PLC system tab of the PLC parameter dialog box.
Set a value within the range of 0.2ms to 1.0ms in increments of 0.1ms.
*8: To use the intelligent function module interrupt, the intelligent function module setting (interrupt pointer setting) is required in the PLC
system tab of the PLC parameter dialog box. (For interrupt from an intelligent function module, refer to Section 6.23.)
*9: I50 has the highest priority (priority 2), and I255 has the lowest priority (priority 207).
*10: When I49 is set in the PLC parameter dialog box, do not execute other interrupt programs (I0 to I48 and I50 to I255) and fixed scan
execution type program.
Once a program such as the fixed scan execution type program is executed, the interrupt program of I49 cannot be executed at the
specified interrupt intervals.
